They may be small and cute, but packs of stray Chihuahuas have been wreaking havoc on the streets of Phoenix, Arizona.

Maricopa County Animal Care and Control says last year alone it received 6,000 calls from the Maryvale section of Phoenix about abandoned Chihuahuas roaming the streets in the neighborhood and scaring children.

‘We compared the number of calls we got in 2013 from that area to similar areas in town and the calls from Maryvale were three times higher than surrounding areas,’ said Melissa Gable with MCACC. ‘Part of it is these animals aren’t spayed or neutered, so they’re out looking for a mate and are having babies, which also contributes to the problem.’

Officials said they do not have enough staff to respond to all the service calls coming from residents in Maryvale.

Gable encouraged people to contain strays in their yards before calling animal control to come and pick them up, the station ABC15 reported.

The infestation of ditched dogs is creating unsanitary conditions in the area since the strays leave behind feces that no one is willing to clean up.
